Planets Around Solar Twins/Analogs (PASTA) I.: High precision stellar chemical abundance for 17 planet-hosting stars and the condensation temperature trend

Qinghui Sun, Sharon Xuesong Wang, Tianjun Gan +30

The Sun is depleted in refractory elements compared to nearby solar twins, which may be linked to the formation of giant or terrestrial planets. Here we present high-resolution, hi…

TOI-2379 b and TOI-2384 b: two super-Jupiter mass planets transiting low-mass host stars

Edward M. Bryant, Daniel Bayliss, Joel D. Hartman +31

Short-period gas giant planets have been shown to be significantly rarer for host stars less massive than the Sun. We report the discovery of two transiting giant planets - TOI-237…
